Contribution

It provides explicit solutions for fermionic zeromodes in heterotic fivebrane backgrounds, including their gravitino components, and suggests a new gravitino pair condensation scenario.

Findings

Two normalizable fermionic zeromodes found

Each zeromode has a non-zero gravitino component

Proposes a scenario of gravitino pair condensation

Abstract

We investigate the explicit form of the fermionic zeromodes in heterotic fivebrane backgrounds. By explicitly solving the fermionic field equations in fivebrane backgrounds, two normalizable and physical fermionic zeromodes are obtained. Each of these zeromodes has a non-vanishing gravitino component. We suggest a possible scenario of the gravitino pair condensation.
